Hi,
from my point of view importing a GPX only as overlay should have no influence on the name proposal in the next export.
But currently the name of the overlay GPX is the proposal for the next export.
Reason: I opened a .kurviger file as route, modified the route and opened a recorded track file as overlay to compare route and recorded track.
The result was ok, so I selected export to save the route. The name proposal was the name of the track file, but usually (>95%) I want to save the route with a name similar to the previous route file.
Regards
Markus
